Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

The first embodiment:

please refer to fig. 1 and fig. 2 in combination, wherein fig. 1 is a diagram of a rolled finished product of a first embodiment of a heat-sealable woven fabric FFS roll bag provided by the present invention; fig. 2 is the utility model provides a different face stack schematic diagram when the tube-shape is made in the heat-seal of sheet woven fabric.

A heat-sealable woven cloth FFS roll bag comprising:

the bag comprises a bag body 1, wherein the bag body 1 is rolled into a cylindrical shape;

the inserting edges 2 are arranged on the two cylindrical sides formed by the bag body 1;

and welding seams 3 are arranged at the staggered positions of the cylindrical edges formed by the bag body 1.

The bag body 1 is a heat-sealable woven fabric, and the bag body 1 is of a sheet structure.

The cylindrical connection position after the bag body 1 is formed is connected in a different-surface overlapping mode, and the upper and lower overlapped positions of different surfaces are subjected to heat sealing.

The utility model provides a but cloth FFS reel bag is woven in heat-seal's theory of operation as follows:

the bag body 1 is rolled into a cylindrical shape, and two end faces are kept to be overlapped;

inserting edges 2 are formed at two sides of the cylindrical bag body 1;

after the overlapping, the heat sealing is performed on the overlapped surface by adopting an FFS process to form a welding seam 3.

the woven cloth packaging bag with higher cost performance can be used for an FFS high-speed full-automatic packaging line, the packaging efficiency of the woven cloth packaging bag is improved, and the FFS packaging process is provided with a high-performance and low-cost packaging material selection.

The second embodiment:

referring to fig. 3 and 7, a second embodiment of the present application proposes another heat-sealable woven cloth FFS roll bag based on the heat-sealable woven cloth FFS roll bag provided in the first embodiment of the present application. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment does not affect the implementation of the first embodiment alone.

Specifically, the difference that the cloth FFS reel bag was woven in heat-seal that the second embodiment of this application provided lies in, but cloth FFS reel bag is woven in heat-seal still includes easily tearing indentation 4, easily tear indentation 4 set up in on the lower plane of 1 upper and lower coincidence of bag body, easily tear indentation 4 and follow the direction parallel distribution of welding seam 3, the upper plane of 1 upper and lower coincidence of bag body is provided with encloses flange area 5, enclose flange area 5 and shelter from easily tear the top of indentation 4.

Through setting up easily tearing indentation 4, facilitate for opening after 1 self encapsulation of bag body for opening of bag body 1 can not produce the piece or the corner of tearing, reduces the production of discarded object, when bag body 1 is in the packing state, encloses that sideband 5 can shelter from and protect easily tearing indentation 4 provides.

The easy-tearing indentation 4 facilitates opening of the bag body 1, avoids generation of scraps or corner wastes when the bag body 1 is opened, and can recycle the complete bag body even if the bag body is opened.

The easy-tearing indentation 4 is of a non-penetrating structure and can keep the integrity of the bag body 1 in use.

The edge enclosing belt 5 can shield the easy-tearing indentation 4 when the bag body 1 is not opened, so that a protection effect is formed.

The easy-tearing indentation 4 is composed of notches which are uniformly distributed, the depth of each notch is half of the thickness of the bag body 1, and the interval between every two adjacent notches is 2-3 mm.

In an alternative way, the notch is a rectangular structure, and the rectangular notch is a conventional easy-tearing structure, so that support is provided for the use of tearing the bag body 1.

In another alternative mode, the notches are in a diamond structure, and the notches in the diamond structure are in an optimized easy-tearing structure.

Referring to fig. 7, in an optional manner, the easy-to-tear indentations 4 are disposed on the upper plane of the bag body 1, the easy-to-tear indentations 4 are directly exposed on the outer surface of the bag body 1, when the bag body 1 is made of a plastic material, when the formed bag body 1 is wound and rolled, the rolling surface of the bag body 1 can be stably compressed and adsorbed on the easy-to-tear indentations 4, and after the bag body 1 is rolled and tightened, the easy-to-tear indentations 4 can form a relative adsorption effect with the surface contact points of the bag body 1 wound, so that the bag body 1 can be more stable after being wound and rolled, and a loose phenomenon cannot occur.

The heat-sealable woven fabric FFS roll bag provided by the embodiment has the beneficial effects that:

through setting up easily tearing indentation 4, facilitate for opening after the encapsulation of bag body 1 itself for opening of bag body 1 can not produce the piece or the corner of tearing off, reduces the production of discarded object, when bag body 1 is in the packing state, encloses keeping off side band 5 and can provide sheltering from and protecting easily tearing indentation 4.

The above-mentioned only be the embodiment of the present invention, not consequently the restriction of the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transform made of the content of the specification and the attached drawings, or directly or indirectly use in other relevant technical fields, all including in the same way the patent protection scope of the present invention.
